Final answer:
The nurse should include giving the child responsibility around the house in anticipatory guidance for parents of a beginning school-aged child.
Step-by-step explanation:
In planning anticipatory guidance for parents of a beginning school-aged child, it is MOST important for the nurse to include giving the child responsibility around the house. This encourages the child's development of independence and a sense of accomplishment. By assigning age-appropriate household chores, such as setting the table or feeding a pet, the child learns valuable skills and develops a sense of responsibility and contribution to the family.
